LaserSharp® Perforating for Breathable Packaging

LaserSharp FlexPak Services offers precision laser perforating services for breathable packaging. Unlike mechanical perforating methods which can puncture or rip flexible packaging films, laser perforating produces cauterized microperforated patterns of round holes, with controlled size and location. Additionally, by using a noncontact laser process, perforated holes are clean and free of processing fragments. This process has been proven for perishable foods and applications such as modified atmosphere packaging (MAP), microwaveable steam release features, venting, and rapid-fill packaging.

Laser microperforating extends the shelf life of perishable foods by improving the atmosphere and controlling the amount of oxygen, carbon dioxide, and moisture inside the package. This process will also aid in the reduction of condensation and bacteria growth while keeping a product fresh with improved flavor. Consistent laser perforated holes enhance both the appearance of a package and its effectiveness in maintaining specific barrier properties which preserve a package’s contents. LaserSharp FlexPak Services will help you incorporate laser processed features in your package design process in order to maintain specific oxygen transmission rates. OTR testing is also performed in-house to ensure accuracy.

Additionally, partial perforations can be used to maintain a hermetic seal. In this case, the laser beam only partially penetrates the film without creating a hole all the way through the material. This allows gas and air to slowly exchange, while protecting the contents from outside contaminants. As opposed to inconsistent mechanically perforated holes that often vary in size, the LaserSharp® process delivers uniform laser microperforations to enhance the quality of the packaged foods by precisely regulating oxygen, vapor and gas transmission rates.

Laser microperforating can also be used to produce controlled venting in rapid-fill packaging to increase product stability during palletizing, storage, and transportation. LaserSharp Flex Pak services will work with you to develop a breathable packaging solution that suites your unique application. Additionally, it is simple to combine laser perforating with other processes such as laser scoring to create easy open features in breathable packaging.
